Research Abstract

We recorded pattern reversal visual evoked potentials(PVEP), and describing below became clear. PVEP is affected in stimulus pattern size. PVEP is affected in refractive power of examined eye. Although PVEP is not subject to big influence in shallow anesthetic depth, a PVEP waveform disappears in deep anesthesia.
PVEP was recorded based on these things and calculate visual acuity in healthy Beagles. It was showed that healthy Beagles have 3.6 cycle per dgree or more visual acuity.
